Description

Technical Field

[0001] This utility model relates to the field of high temperature setting machine technology, and in particular to a pre-drying device for a high temperature setting machine. Background Technology

[0002] In traditional dyeing and printing processes, washed or dyed fabrics need to undergo dehydration to reduce surface moisture. However, before entering the high-temperature setting machine, a chemical addition process (using diluted auxiliaries) is usually required to enhance the fabric's finishing effect. While necessary, this chemical addition step causes the already dehydrated fabric to reabsorb water, significantly increasing its moisture content. This high-moisture fabric then needs to undergo prolonged drying and setting in the high-temperature setting machine. This process not only consumes a large amount of energy but also limits the machine's operating speed, thus impacting overall production efficiency. Utility Model Content

[0003] To address the problems mentioned above in the background art, this utility model provides a pre-drying device for a high-temperature setting machine.

[0004] The solution adopted by this utility model to solve its technical problem is: a pre-drying device for a high-temperature setting machine, including a frame for docking with the high-temperature setting machine, a pre-drying channel provided in the frame, and a transmission mechanism provided in the pre-drying channel for carrying and guiding the fabric. The transmission mechanism includes a conveyor belt that runs along the direction from the inlet to the outlet of the pre-drying channel. A drying mechanism for drying the moisture of the fabric is provided above the conveyor belt. A heat equalization mechanism for promoting uniform heat distribution in the drying channel is provided above the drying mechanism.

[0005] By adopting the above technical solution, a drying mechanism and a heat equalization mechanism are installed in the drying channel, which can effectively heat the fabric and accelerate the evaporation of its internal moisture. Furthermore, the conveyor belt installed in the drying channel can slowly carry the fabric forward, preventing it from being scorched by the high temperature. This, in turn, improves the working efficiency of the subsequent high-temperature setting machine and increases its production output.

[0006] Furthermore, the drying mechanism includes a mounting frame arranged parallel above the conveyor belt and multiple heating tubes installed in the mounting frame, with each heating tube evenly distributed along the width direction of the conveyor belt.

[0007] By adopting the above technical solutions, it can be ensured that all parts of the fabric receive the same intensity of heat radiation, thereby improving the uniformity of drying.

[0008] Furthermore, the heat equalization mechanism includes at least one axial flow fan disposed above the heating tube, wherein the airflow direction of the axial flow fan is consistent with the heat source direction of the heating tube.

[0009] By adopting the above technical solutions, the heat emitted by the heating tube can be quickly and evenly distributed throughout the pre-drying channel, avoiding local heat accumulation or heat loss, thereby accelerating the evaporation of moisture from the fabric surface.

[0010] Furthermore, the transmission mechanism also includes a passive roller for guiding material into the drying channel, an adjusting roller group for fine-tuning the position of the conveyor belt, a support roller group for supporting the conveyor belt, a tension roller for maintaining the tension of the conveyor belt, and a drive roller for driving the conveyor belt to operate.

[0011] By adopting the above technical solutions, the passive roller can guide the fabric smoothly into the pre-drying channel, the adjusting roller group can correct the left and right deviation of the conveyor belt, the support roller group can support the conveyor belt, the tension roller can maintain the tension of the conveyor belt, and the drive roller can drive the conveyor belt.

[0012] Furthermore, the conveyor belt is a nylon mesh conveyor belt, which is wound around the passive roller, adjusting roller group, support roller group, tension roller and drive roller.

[0013] By adopting the above technical solutions, the nylon mesh conveyor belt can remove the moisture generated during drying, reducing the drying time.

[0014] Furthermore, the frame is also equipped with a control system for controlling the heating tube and the axial flow fan. The control system includes a temperature sensor located in the drying channel, and the temperature sensor is signal-connected to the heating tube.

[0015] By adopting the above technical solutions, precise temperature control can be achieved within the drying channel.

[0016] In summary, the beneficial effects of this utility model are as follows: By setting an axial flow fan above the heating pipe in the drying channel and ensuring that the fan direction is consistent with the heat source direction, the directional airflow generated significantly enhances heat conduction and convection effects, accelerates the evaporation of moisture on the fabric surface, and allows the fabric to undergo good pre-drying treatment before entering the high-temperature setting machine, effectively increasing the working speed of the setting machine and thus improving the overall production efficiency.

[0021] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

Unless otherwise stated, "a plurality of" means two or more.

[0023] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or signal connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1 to 2 As shown, a pre-drying device for a high-temperature setting machine is provided. In this embodiment, it includes a frame 1 for docking with the high-temperature setting machine, a pre-drying channel 2 provided in the frame 1, and a transmission mechanism provided in the pre-drying channel 2 for carrying and guiding the fabric. The transmission mechanism includes a conveyor belt that runs along the direction from the inlet to the outlet of the pre-drying channel 2. A drying mechanism for drying the moisture of the fabric is provided above the conveyor belt, and a heat equalization mechanism for promoting uniform heat distribution in the drying channel is provided above the drying mechanism.

[0025] In this embodiment, the frame 1 provides a stable structural support for the entire equipment. A drying channel is installed within the frame 1, with an outlet and an inlet on each side. The outlet connects to the inlet of the high-temperature setting machine, allowing for pre-drying of the fabric entering the machine. A drying mechanism is installed within the drying channel to heat the fabric, accelerating the evaporation of internal moisture. A heat equalization mechanism above the drying mechanism ensures even heat distribution within the pre-drying channel 2, preventing localized overheating or uneven heat distribution. This guarantees the quality and efficiency of the fabric during the drying process, preparing it for subsequent high-temperature setting. Furthermore, a conveyor belt within the drying channel carries the fabric forward slowly, preventing it from being scorched by the high temperature.

[0026] like Figure 2 As shown, the drying mechanism of this embodiment includes a mounting frame 41 arranged parallel above the conveyor belt and multiple heating tubes 42 installed within the mounting frame 41. The heating tubes 42 are evenly distributed along the width of the conveyor belt. By providing a mounting frame 41 parallel to the conveyor belt within the drying channel and installing multiple heating tubes 42 within the mounting frame 41—in this embodiment, these are steam heating tubes 42, which provide uniform heating and are relatively inexpensive, but vacuum electric heating tubes 42 with fast heating speeds can also be used. The even distribution of these heating tubes 42 along the width of the conveyor belt ensures that every part of the fabric receives the same intensity of heat radiation, avoiding "hot spots" or "cold zones" during the drying process and improving the uniformity of drying.

[0027] like Figure 1 As shown, the heat equalization mechanism in this embodiment includes at least one axial flow fan 5 positioned above the heating tube 42, and the airflow direction of the axial flow fan 5 is consistent with the heat source direction of the heating tube 42. In this embodiment, an axial flow fan 5 is positioned above each heating tube 42, ensuring that the airflow direction of the fan is consistent with the heat source direction of the drying mechanism. Specifically, the axial flow fan forces the hot airflow generated by the heating tube to convect along the conveyor belt's running direction, forming a directional circulating airflow. This allows heat to be evenly diffused to all areas of the pre-drying channel, preventing localized heat accumulation. The directional airflow generated by the axial flow fan 5 enhances heat conduction and convection effects, accelerating the evaporation of moisture from the fabric surface.

[0028] like Figure 1As shown, the conveying mechanism in this embodiment also includes a passive roller 32 for guiding material into the drying channel, an adjusting roller group 33 for fine-tuning the position of the conveyor belt, a support roller group 34 for supporting the conveyor belt, a tension roller 35 for maintaining the tension of the conveyor belt, and a drive roller 36 for driving the conveyor belt. The conveyor belt is wound around the passive roller 32, adjusting roller group 33, support roller group 34, tension roller 35, and drive roller 36. The passive roller 32 is located at the entrance of the drying channel and can smoothly guide the fabric into the pre-drying channel 2, ensuring that the fabric can be laid on the conveyor belt. The adjusting roller group 33 can correct the left and right deviation of the conveyor belt, ensuring the alignment and stability of the fabric throughout the drying process. The support roller group 34 can support and lift the conveyor belt, and the tension roller 35 maintains the appropriate tension of the conveyor belt, while the drive roller 36 can drive the conveyor belt to move. Furthermore, the conveyor belt is a nylon mesh conveyor belt 31. Specifically, the temperature control range of the pre-drying equipment is 80-180℃, and the nylon mesh conveyor belt is made of high-temperature resistant modified nylon material (temperature resistance ≥200℃), ensuring long-term stable operation within the preset temperature range. It possesses good flexibility and a mesh structure that allows air circulation and liquid penetration, enabling the expulsion of moisture generated during drying and preventing moisture accumulation on the fabric surface, thus reducing drying time.

[0029] Furthermore, in this embodiment, the frame 1 is also equipped with a control system for controlling the heating element 42 and the axial fan 5. This control system includes at least one temperature sensor installed within the drying channel, and the temperature sensor is signal-connected to the heating element 42. The temperature sensor, located within the drying channel, can monitor temperature changes within the channel in real time and promptly feed back the monitored temperature signal to the control system. Based on the set drying temperature and the real-time monitored temperature value, the control system intelligently adjusts the power output of the heating element 42 and the axial fan 5 to achieve precise temperature control.

[0030] In summary, the beneficial effects of this embodiment are as follows: By setting an axial flow fan 5 above the heating pipe 42 in the drying channel and ensuring that the fan direction is consistent with the heat source direction, the generated directional airflow significantly enhances heat conduction and convection effects, accelerates the evaporation of moisture on the fabric surface, and allows the fabric to undergo good pre-drying treatment before entering the high-temperature setting machine, effectively increasing the working speed of the setting machine and thus improving the overall production efficiency.

[0031] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
